About this blog
What you will and will not find here.
Is this a news site?
No. Prepful only publishes pieces that map to a tool or a product page: score explainers, format guides, and how-to sequences. We do not run What is the SAT encyclopedia posts.
Who writes these articles?
Prepful. There is no invented expert byline. Numbers on scores come from the same percentile table as the calculator and chart.
